To alt whom it may conloem:

Be itknown that we, ZoLTAN B. Csrnr, 'T Aco KRONELEIM, and ZoLTANTAM'Assv, residing atCleveland, in the ooh invented certain new anduseful Improvements in Conrtible Chairs, of which the following is aspecification.

Our invention relates to convertible chairs,

and is'an improvement in that' class of vchairs wherein the seat andback of the chair lis inverted to form a bed, all as hereinafter`described and more particularly pointed out 1n the claims. i

5 In the accompanying drawings, Figure l is a 4perspective view ofthechair when folded, and Fig. 2 is a vertical section thereof showing thesprings` and bed `mattress particularly. Fig. 3 is a vertical ,sectionon line .1v-m, Fig. 4, and Fig. 4 is a sectional view on line 'zyy, Fig.3 -showing the skeleton frame more particularly and with theVupholstering springs and mattress removed. Fig. 5 is a plan view of theframe parts unfolded for use as a bed and with the side arms lowered andbroken away in part,` and 6 is a longitudinal section centrally of Ourlinvention comprises -an open base frame -2- of rectangular or squareformation supported by legs --3-A at its four corners, and the ysidepieces -4; of said frame are preferably and approximately double theheight of crosspieces 54. An' open seatframe 6- corresponding in sizeand shape to base frame -2-, is hinged at -7- to the front end of sidepieces Llthereby permitting said seat frame to either' rest Hush uponbase frame Q-f, or be inverted 40 to the samehorizontalplane at thefront thereof. `lhen .inverted cross piece --8- of seat frane'j-GQ-abuts against front cross piece -5- ofbase ,frame -2- to maintainhorizontal alinement between said frames. -A

4l-f, respectively, are adapted to stand upright in more or lesslparallel relationship tok jointly form the back of the chair.,

To Vdistinguish between. these two back nty of Cuya-l freedom for theoccupant 'o frames, frame 9 will behereinafter referred horizontal planeas shown 1n Fig.j6. In so z doing a pair of legs +13- pivotallymountedinside yrecesses i4-.- on seat back 9 are caused to drop by gravity toavertical supporting position for seatback l-f9-, and

a' similar pair of legs (not shown) may be used fore seat frame 6 ifdesired, but the shouldered joint at hinges --10- is deemed sufficientto produce .a rigid supporting frame for the purposes required. p

Hinged back rest ,-1lis adjustably supported at different inclinationsby a curved ratchet link -15 pivotally secured to cross piece -i6-- ofthe restframe, and

-which link is adapted to lockingly engage slotted keeper. 17- fastenedto the rear face of cross piece -5-1of base frame ,-2-. A. cable 1S-attached to linke-'15- ex` tends to an operating lever '-'19- `pivotallymounted to the upper cross piece e-20- of back rest- -ll-e, and whichlever is provided with a button or stem -2ladapted to project through anopening in said cross piece and where it may be engaged and de` pressedby .the finger or hand to lift' link -l5- free of keeper -fl7- andpermitV raising or lowering of back rest -11- to any desiredinclination.' Link y--15- may either `lock by gravity orbe springpressed` to the same end.

A further feature of the invention is embodied in. the drop side arms.-22-f at either side thereof, and ,which are lowered to a horizontallane when the parts are unfolded to form a ed.` Thus, each arm -22-is'preferably smooth and. plainlts full height and lenth on .the inside:tace` thereof ywhere it 'aabuts and reshts Hush against the sides' ofthe frameparts, so that -when said arms are lowered each may provide atable `or stand at either side of the Yhed at the head thereof. Inaddition, the

lowering ofv said" side arms 1pinail'jtesC-lgreterf e an v1 novother`advantage were afforded by their l use, this alnegwould vbe noteworthy.

Lowering and raising of-arms -`22.'- is' obtained-by a pairof cables 24and 25, re-z spectively, afset for each at 'either side ofy base. frame-2 Each cable '-24- conel rigidly affixed to eacharm -,-22-- and eX-tending downwardly. and vinwardly beneath hinges -23-, there-'being'anopening -1-28-4 provided therefor, at'tlie bottom ofside pieces -4 Theother end-of -each cable--2 after passing over a sheave -29- isattached. at pointsfBO- onthe linside of'jseat frame- '-'-6-" andrelatively near `to the'pivotal point of hinge -7 so However, thislowering 'of the vside armsis not immediate, there being a relativelygreater and faster movement of seat frame' 6 at its free end than Iwhere cable -24 `is attached at point 30", and the natural slack in .thecable must also'be taken 'up before an actual pull is hadupo'n projec-Thisv gives -an interval of rest for the side arms during initial'unfolding `of seat frame f5- which is taken advantage. of to disengagetwo locking hookmembers .-land -32-, mounted on` vffs'pectively, seeFig. 3.v Said hooks 4pivotally lock the side arms to the seatframewhen yhaving a seat frame hinged thereto at lts the parts are folded foruse asa chair, Otherwise, any voutward pressure upon the arms would strainrthe cables and their conf nections. connectv with projections -27f andvpass on one side to yprovide a'. cushioned and fin having an mver'tible,seat frame and drop tachingl with seat frame 6-v at corners mediatelybeneath projections -27- to to lift'arms -22-. v Obviously, Vwhen cables'-2tare under tension to lower arms 22, cables 25- are 'slackened,' and'frame, in combination witha s et of cable 'connections between saidarmsand i' ,seat
